canon rumors FORUM

I haven't seen anything that mentions an actual availability date yet for the UK. I think it's finally time to take the plunge and spend some money, I think the 7DII will end up being out of my price range at the moment. This seems like a fantastic upgrade for the 400D and generally looks like a very capable camera with some decent features.

Having not had the joys of video, live view or many of the other features, I feel this alone will provide quite the learning curve. Bit annoying that I'm going to have to go out and buy a whole load of SD cards now though! At least the wife can have the old camera and keep all the old CF's.

Other than Canon's official videos, how long would it normally be before this is in the hands of independent reviewers so that we can start to get some decent, hands-on video reviews? Written articles are all well and good, but my patience for some of them runs out pretty quickly!

Pretty darn nice camera! I like it. However, if it has a smaller body than the 60D, I really consider the camera a Super Rebel. The inclusion of SD card, lack of headphone jack and non-replaceable focus screen keep it at a Rebel level. This camera is not on the same level as the 50D.

For professional use, the small body is a deal-killer for me. It has some great technology and features which will make the higher-end amateur market happy.

"Just a silly little millimeter." I believe that was the ad line used by a cigarette seller many years ago. They increased the size of their cancer sticks to 101 mm from 100. This obviously made them so much better.

Here are the dimensions that are so troubling to you:

50D:146X108X74 (vol. 1.167)

60D:145X106X79 (vol. 1.214)

70D:148X111X74 (vol. 1.216)

The trend line would appear toward larger cameras. But, just a few silly little millimeters.

Is AFMA even necessary with the new focusing system? I'm just wondering. I got the impression that since the sensor itself is confirming the focus, adjustments might be less important.

No, AFMA isn't necessary for the Dual Pixel CMOS AF, nor is it necessary for the Hybrid CMOS AF or good ol' Live View contrast detect AF. But remember that those AF modes which use the CMOS image sensor only operate with the mirror up - not through an optical viewfinder. The 70D has the 19-pt AF sensor (from the 7D) that's used when looking through the VF, and that requires AFMA just the same as any other standard phase detect AF system.

That standard phase detect AF is still the go-to with fast moving subjects, and holding a heavy camera + lens out in front of you for Live View composition isn't always easy - the VF is there for a reason.

This is why I have a hard time believing that the optical viewfinder will ever be rendered completely obsolete- mirrorless cameras certainly are more compact but as you say, for action, framing in bright daylight, and hand holding large lenses, the viewfinder is still the way to go. There is just something about the SLR with grip that feels much more natural to me than using a compact with the screen to compose.

A big deal being made about this new live view focus thing...what I'm interested in is how good the servo mode is. Will this make a good sports camera? Sometimes the reach of 1.6x really comes in handy in those cases. The 60D was competent but hardly impressive. I'm hoping the 70D is a significant improvement in this regard, offering customizability, etc.

I'm a videographer, but I'm thinking about switching from my 5D Mark II to the 70D if the noise isn't too bad. The main reasons is that the 70D has a Digic 5+ processor, which is the same as the 5D3 if I'm not mistaken, right? If the magic lantern team manage to hack the 70D, which I'm sure they are, that could enable 1080p RAW video recording. Also that AF in video recording looks quite handy when its hard to focus manually. Lastly, its a generally better camera, functions wise, than the 5D2, which only has the fullframeness to brag about, which although is really nice, but I could give that up for generally better specs and that lovely processor. :3

ML hack would require CF card. 70D seems to have SD card only so no, there would be no 1080 raw video for 70D.

ML made a hack for the 6D which is also SD card so Im not sure where you are getting your information.

Not to mention they have stable versions available for the 50D, 60D, 500D, 550D, and 600D; and Alpha versions for the EOS-M and 1100D which, correct me if I'm wrong, all use SD. IMO, this will make a phenomenal video/stills camera hybrid for consumers/prosumers getting into the field, with downsides being no 60p or headphone jack.

Depending on its ISO performance, this little guy will make for a great backup crop body to my 6D for its speedier AF system, video features (hopefully significantly less moire/aliasing), and of course 1.6x crop factor!

Has anyone seen any 6400+ ISO samples and/or any mention of its noise performance? In a few of the pre-production reviews, they mention it is equal to or better than the 60D/7D, but that's not saying much

Well, it has the 7D's AF sensor - I'd expect AI Servo performance on par with the 7D, i.e. very good.
